nnrmennaaioa.

To all whom t may concern:

Be i known that I, GEORGE' F. Timur, a citizen of the United States,` residing at Flint,lin the county of-Genesee and State of 'Michigam have invented certain new vand.

useful improvements in Refrigerators; and lf do hereby, declare the following to be a full, clear, and exact descriptionof the inas will enable others skilled and use the same. l

rlhe inventiony relates topa refrigerator.

rlhe object of the present, invention is to f improve the construction of refrigerators and to provide a refrigerator of simple,

practical and comparatively inexpensive construction adapted to ybe maintained in a cool sanitary condition without the use of" ice and 'adapted'. also to have the atmosphere readily changed when desired so that the refrigerator will contain fresh, dry,cool,air. #A further object of the invention is to provide' a refrigerator of this character equipped ywith means foravmaintaining a constant circulation of cool air throughout the refrigerator so as' to produce a uniformly cool temperature in all portions of the re-l frigerator. With these and other objects in view, the

invention consists inthe construction, and

novel combination `of parts hereinafter fully l.

' described, illustrated in the accompanying drawing, and pointedout in the claims hereto appended; it being understoodthat various changes in the' form, proportion, size., and minor details of construction, vwithinv the scope ofthe claims, may be resorted to without' departing from the spirit or sacrilicing any of the advantagesl of the invention.

` In the drawingv 'l Figure 1 is a vertical sectional view of-arefrigerator constructedvin accordance with, this invention, i

. `in the accompanying course in practicaba made upof any (ie-- sired number of sections to facilitate the inrammen may a. reis.

the invention, 1 designates a refrigerator dei signed to be mounted in a house and located in the kitchen or other portion of the same upon the first floor -2 and provided with -horizontal shelves: S-arranged at intervals and provided with openings 4 to permit the air to circulate through them'from the bottom to the top of the refrigerator. l The refrigerator is also provided adjacent to the top with a horizontal partition 5 terminating short of the side walls of the refrigerator to provide side openings 6 and extending downwardly from the top portion of the refrigerator 'is a vertical Warm air pipe 7 connected at its upper end to the horizontal and a-n opening 8 thereof. The

downwardly partition 5 warm air pipe 7 extends through the 'bottom 9 'of the refrigerator and through -the basement or cellar under the house into the ground, about ten to thirty feet so that the ground will be suiiciently Acold during all seasons ofthe' year to cool the air passing through -the vertical pipe?.

The warm air pipe extends into an outer pipe 11 of greater diameter than the pipe 7 to provide'a surrounding space 12for the upward passageof the air 4from the lower end of the warm air pipe. The outer pipe 11 is provided at its lower end with a cap L3 or other suitable closurenand the upper end ofthe said pipe 11 extends through the bottom of the refrigerator and projects` above the same. and terminates beneath. an annular hoodf 15 which formsl both 'a'shield and a deflector for directing the cold air outwardly. The hood also prevents arrything within the refrigerator from droppingdown the outer pipefand interfering .with

the circulation of, air through the same. The hood 15 is provided with a raised central 'portion 16 Which is suitably secured to the wamn'lairpipe above the upper endof the outer pipe 11. The inner warm air pipe. ,is supported within the outer pipe at spaced points by spiders 17 which maintain the inner warm air pipe in properl spaced rela- While vthe inareshown continuous ner and outer pipes drawing they may of stallation of the warm and cold air pipes as will be readily understood. The exposed portion of or cellar 10is provided with an outer covering 18 of asbestos or other Suitable ma.-

the o uter pipe at thev basementv terial which is aI non-conductor o f heat to v prevent vthe temperature of the basementor" cellar from affecting the air passing through the outer cold air pipe. The air from the tively through the inner warm air tube by means' of a fan 19 arranged within a suitable casing 20 and connected with an electric mo- A tor so that the desired amount of tor 21'preferably mounted uponthe top of the refrigerator and having its shaft 22 ex# vtending through the top of the refrigerator.

The fan casing is provided at the top with an inlet opening or eye 23 and it has a bottom opening 24 which 'registers with the opening in the horizontal partition upon 'which the fan casing is mounted.

The refrigerator is provided in its to-p with Ventilating openings 25 from which extend approximately L-shaped ventilator 'tubes 2.6 having pivoted dampers 27 adapted to control the inlet ofair into the refrigeraure fresh air may be admitted to the re rigerator. The electric motor'may be of any desired construction and will be supplied with current .from any ordinary fixture and whenv the fan is operated the warm air from'the top of the refrigerator will be driven through the inner warm airpipe and expelled from the lower end thereof and caused to rise or pass upwardly through the cold air pipe where it will be chilled and introduced into the refrigerator at the bottom thereof. The cold air from the upper end of the outer /pipe will vpass upwardly throughv the openings in the horizontal shelves and will be drawn in by the fan and a continuous circulation of cool air through the refrigerator will be maintained while the fan is in operation. Alsothe ventilating devices' will enable the y atmosphere Within the refrigerator to be changed as required or desired.` The. upper horizontal I 1 partition 5 is arranged in spaced relation with the top of the refrigerator to form an air chamber 28 and the openings 6 at opposite sides of the chamber will permit the air to enter the said chamber from both sides of the refrigerator, but openings may be provided at anyother desired pointsl as will be readily understood.4 The warm air pipe 1s preferably. provided within the refrigerator` with upper and lower elbows 29 and 30 totop. -of the refrigeratorv is circulated posibottom thereof`and extending downwardly therefrom .and being of sufficient length to extend into the ground so as to be chilled thereby, and a warm air pipeconnected at its upper end with a casing', a fan within the casing, said pipe extending downwardly throughv the refrigerator into the cold air pipe and arranged to discharge air into the cold air pipe at the bottom thereof.

2. The combination with a refrigerator.

provided at the top with an air chamber communicating with the interior of the refrigerator, of a cold air pipe communicating at its upper yend with the refrigerator at 'the bottom thereof and extending downwardly therefrom and being of sufficient length to extend 'intothe ground so as to be chilled thereby, a warm air pipe .connected at its upper end with a casing, a fan Within the casing, said pipe extending downwardly through the refrigerator into the cold air pipe and arranged to discharge air into the cold air pipe at .the bottom thereof,I said cold air pipe projecting above the bottom of the refrigerator, and a hood mounted on the warm air pipe and extending over the upper end'of thevcold air pipe in lspaced relation with the same and projecting below the upper edge thereof.

In testimony whereof I aflix my signature in the presence of two witnesses.
